The Night of the Camera - S4.E10

Agent West raids a local warehouse in an attempt to apprehend a suspected opium gang member. As he struggles with the suspect, a new secret agent named Bosley Cranston rushes in and attempts to help. Unfortunately, he only makes matters worse, accidentally toppling a piano crate on the suspect and killing him. Cranston, however, is not the meek incompetent he appears and later surprises his colleagues with his karate skills and his popularity with beautiful women.
